Sunbathing on the beach
沙灘日光浴
Scenario: Sunbathing gives us a healthy tan, but overexposure to the sun’s rays can do more harm than good to our skin.
適用情境：日光浴能為我們帶來健康的小麥色肌膚，然而，過度暴曬則弊大于利。

SPF requirement: 50 or more
防曬系數: ≥50

Solution: Keep in mind that you need the strongest sun protection you can get. Look for a thick sunscreen with an SPF of at least 50 that offers broad-spectrum protection. Or better still, a waterproof one that will give you longer-lasting protection. Don’t forget to reapply it every 60 minutes, or whenever you sweat or get wet.
防曬建議：這時候，你需要最強效的防曬保護：一層厚厚的防曬霜，其防曬指數不得低于50，并且要能抵擋所有波長的紫外線。當然，要想取得更好更持久的防護，你需要選擇具有防水功能的防曬霜。最后，別忘了每1個小時，或是每次你出了汗的時候都重涂一次防曬。
